System for product authentication by mobile phone

Abstract

An authentication system enabling a customer to verify the authenticity of a product in a foolproof, secure and simple manner. plurality of secret sets of numbers is generated, each set comprising a challenge portion and a response portion. These sets are stored on a remote server. Each set is associated with a different product. The customer sends a challenge portion to the server, and prompts the server to provide a response. If the response matches that of the product in hand, the product is known to be authentic. In another embodiment of the system, cellular transmission is used to power an electronic tag attached to the product and carrying authentication data. In a third embodiment, the full manufacturer database is divided into separate databases, possibly related to product vendor, such that an authentication process can be performed without the need to access the manufacturer's entire database of products.

Description

FIELD OF THE INVENTION[0001]The present invention relates to the field of product authentication, especially with regard to the determination whether a product bought by a customer is an authentic product or a fake, and with regard to secure methods of communication for product authentication and tracking.BACKGROUND OF THE INVENTION[0002]Many companies suffer from counterfeit products produced by pirate manufacturers and their distributors. These fake products are manufactured to look like the authentic original products, but are in fact not so. Counterfeiting is a major problem in many market segments—pharmaceutical drugs, cosmetics, cigarettes, jewelry, clothing & shoes, auto parts. Tens of billions of dollars of counterfeited products are sold every year, resulting in huge losses to the manufacturers of the genuine products.[0003]Currently, although a number of means are used to validate the authenticity of products, such methods are not always reliable or user friendly for the p...

Benefits of technology

[0011]The present invention seeks to provide a new authentication system that overcomes some of the disadvantages of prior art systems, from a number of aspects. According to the various embodiments of the present invention, the system enables a customer to verify the authenticity of the product he has or is going to purchase, in a foolproof, secure and simple manner.

[0013]Therefore, according to this first preferred embodiment of the present invention, the number set preferably comprises at least a pair of character sequences, one of which is a challenge sequence, which the customer sends to the supplier's remote central register of numbers, preferably stored on a remote server, and another is a response sequence, predetermined to be associated with that specific challenge sequence, and stored on the remote central register of numbers. The Remote Checking System then sends back the response sequence matching the challenge sequence. If the returned Response sequence matches the second sequence of the number set associated with the product in his hand, the customer knows with high level of probability that his product is authentic. If the response disagrees, the product is likely to be a fake. The Remote Checking System can also optionally apply checks to the Challenge—the most important one being that the response is only generated once—the first time that that particular Challenge is received, thus thwarting attempts to circumvent the system by the wholesale use of a single authentic number set on numerous counterfeit products.

[0017]According to a second preferred embodiment of the present invention, an electronic tag is used for identifying the product being checked. In order to provide the communication link between the tag and the manufacturer's central register of numbers without the need for a dedicated RFID reader, the product is verified using a regular cellular phone. Attached to the product is a secure electronic tag having a secure signature and encryption scheme. The system differs from those of the prior art, in which the tag is powered by means of charging generated from its own short-range communication channel, in that in this invention, the comparatively strong cellular phone transmission signal is used to charge the tag. The tag then broadcasts its information in one of the standard cellular phone short range communication methods, such as Bluetooth, NFC, IR, or similar. The cellular phone transmits the information to a server, which can either have full duplex communication with the tag or it can perform the authentication itself. This method thus enables the powering of a communication device by means of the transmission from a different communication channel. According to further preferred embodiments, the strong cellular transmission can be used to power more than one short range communication channel, each having its own antenna for picking up the cellular transmission, such as Bluetooth and a conventional RFID channel.

[0023]The system of this fourth preferred embodiment can be used for track and trace applications, such that the organization logistics team can determine the exact size, location and status of any item of the stock, spread over numerous locations, yet without compromising the sum total of the organization's stock situation on any one central server.

Problems solved by technology

If the response disagrees, the product is likely to be a fake.
